Blizzard taking Valve to Court
Posted by Mike Malloy on 02.10.2012
The case is in discovery.
Blizzard has filed a Notice of Opposition with the US Patent and Trademark Office trying to block Valve use of the community-promoted word "Dota"
The word has been used exclusively in reference to a (mod of a) Blizzard game, the document Blizzard submitted explains. "By virtue of that use, the DOTA mark has become firmly associated in the mind of consumers with Blizzard, including to signify a highly popular scenario or variant of one of Blizzard's best-selling computer games, Warcraft III."
